I have a 1999 Arctic cat ZL 500 non efi sled that has been stood for 8 years. It started first time on easy start but i could not get it to run on its own. I could see air in the fuel line so i replaxced the fuel pump and removed the carbs. The needle valves? where stuck so i gave the aluminum a tap near the valve and that freed them up. I put the carbs back on and after 4 pulls it fired up and rand for 20 minutes or so although smokey. After the 20 mins it died, I fired it back up it ran for a few mins then died again i tried giving it gas and it still died and sounded like fuel starvation. I went to pull the coil and it felt tight then it wen normal but it would not fire. I took the plugs out and they looked fouled with water and some oil (could be some water in the tank from being stood so long) i put the plugs back in and it was still tight and as i pulled the coil it made a huge backfire. The engine pulls easy with no plugs.
Any suggestions?
Thanks in advance
